If you’re a texter, you’ll love Messages on iPhone, iPad and iPod touch. Now they all come with iMessage, a service that’s an even better kind of texting. Because it’s free for you and anyone texting over Wi-Fi using an iOS device or Mac with iMessage. And it’s unlimited.* So say as much as you want.

iMessage lets you send messages back and forth with anyone on iPad, iPhone, iPod touch or a Mac running OS X Mountain Lion or later. Send photos, videos, locations and contacts, too. If you have more than one Apple device, iMessage keeps the conversation going across all of them. And you can text and send photos and videos via MMS to other mobile phones over mobile networks. Even ask Siri to text for you. Just say “Tell Peter I’m on my way” and Siri writes your message and fires it off.

Send a message to one person or to many friends at once — along with photos, videos or links you like. When someone replies, everyone sees it. With more people you’ll get more texts, but remember, it’s iMessage, so every text is free over Wi-Fi.*

It’s reassuring to know your text was read — or even received. iMessage tells you if your text went through. If the recipient has read receipts enabled, you’ll see that your message was read too. And since no one likes to be interrupted, iMessage shows you when someone’s in the middle of a reply.

On iPhone, when your text bubble is blue instead of green, you’ll know you’re using iMessage instead of SMS. You’ll know that you can get a quicker response. You’ll know that the text session is free. You’ll know it’s been sent to all your recipients’ Apple devices. And you’ll know they received the text. SMS texters will be green with envy.

Turn on iMessage and tap “Use your Apple ID for iMessage”.

Note: iPhone screens shown. On an iPad and iPod touch, you won’t see the screen on the right, you’ll go straight to the Sign In screen below.
